Kangaroos thrive in communities, just like people! They travel together in groups called mobs, which can have anywhere from three to 300 kangaroos. Sometimes kangaroos leave one mob to join another, and the leaders of mobs can change over time. The female kangaroos, called does, carry their babies (known as joeys) in a pouch called a marsupium until the baby roo is about 8 months old and ready to start exploring the world on its own.
Kangaroos are animals that constantly travel. They love to explore the vast grasslands and marshlands of Australia, therefore, as cities continue to expand and more people move to Australia, the kangaroos are forced to share their land with people. This means that kangaroos can sometimes be found in large cities, such as Melbourne. Living near the city is dangerous for kangaroos, since they don't understand road rules like people do! They will often eat grass on the side of freeways, and stop in the middle of roads. Therefore, throughout the outskirts of the city, drivers will find "kangaroo crossing" roadsigns scatterred throughout the highways.
